How travellers perceive the quality of public transport services has profound influence on their satisfaction and thus of their inclination to choose this mode of transport. Punctuality, which may be interpreted as timetable adherence or overall travel time predictability, is often pointed out as the most important constituent of overall service reliability of public transport systems. However, in
The railway transport system has seen an increasing demand in recent years, while delays and missed punctuality goals continue to be problems in many countries. To improve punctuality, the amount of primary delays needs to be decreased, and knowledge of the shares of the different types of delay – entry, run, and dwell – is important to identify the most efficient countermeasures.

The timing of the spring season in the boreal region is shifting under global warming, with profound impacts on ecosystems and hydrological processes. However, the mechanisms driving this transition and its considerable interannual variability are not well described, especially regarding the influence of large-scale atmospheric teleconnection patterns. This study examines the temporal variability
This study examines the long-term socioeconomic impacts of 44 train station openings between 1995 and 2015 across Swedish regions. Using the conditional difference-in-differences estimator developed by Callaway and Sant'Anna (2021), which accounts for variation in treatment effects across time and locations, we evaluate the impact on population, income, education, and unemployment. Twenty years af
This chapter explores performances of emotion regulation through a dramaturgical lens, focusing on occupations with high performative demands. While reviewing research and theorizing on performance, we point to key intersections between sociological studies on emotion management and psychological studies on emotion regulation. First, we focus on the scaffolding of performance, how the script and t
Access is the process of establishing rapport with a field containing different phases without an articulated end. Qualitative research often involves studying people in their social setting, documenting action, and meaning making in relation to the field in which it occurs through ethnographic methods such as observations, shadowing, and interviews. Gaining permission to a site or a specific grou
Data-driven methods provide great potential for future applications in engineering, for example in terms of more efficient simulations. Conventional material models and the associated constitutive equations are substituted by a minimization of a distance between so-called material and mechanical states, which, however, leads to non-unique solutions. The aim of this paper is to analyze the influenc
This chapter analyses humour from an emotion sociological perspective, linking humour to power, status, and group solidarity. It draws from about 300 observed trials and interviews with 43 judges and 41 prosecutors from four Swedish districts courts. Humour is sometimes skilfully used as a strategy to ease tension, relieve boredom or to reprimand. It is initiated/allowed by the judge, but high-staThis chapter analyses humour from an emotion sociological perspective, linking humour to power, status, and group solidarity.

Understanding damage mechanisms and quantifying damage is important in order to optimise structures and to increase their reliability. To achieve this goal, experimental- and simulation-based techniques are to be combined. Different methods exist for the analysis of damage phenomena such as fracture mechanics, phase field models, cohesive zone formulations and continuum damage modelling. Assuming
Bakgrund: Ett mått på följsamhet till paleolitisk kost som inte baseras på populationsrelativa intag av livsmedelsgrupper har hittills saknats. Syftet med denna avhandling var att utvärdera användbarheten av Paleolithic Diet Fraction (PDF), ett nytt mått på följsamhet till paleolitisk kost, beräknat som andelen av det totala intaget av livsmedelsgrupper som utgörs av paleolitiska livsmedelsgrupperAbstract: Background: A measure of adherence to the Paleolithic diet not based on population-relative food group intakes was lacking. The aim of this thesis was to evaluate the usefulness of the Paleolithic Diet Fraction (PDF), a novel measure of adherence to the Paleolithic diet, calculated as the fraction of total food group intake derived from Paleolithic food groups. Methods: PDF was calculate
Background and aimMany patients with depressive disorders do not improve with first-line treatment with selective serotonin inhibitors (SSRIs). Adverse drug reactions (ADRs) are common. However, there are no reliable methods to predict treatment response.The general aim of this thesis was to investigate the role of peripheral serotonin and the polymorphic CYP2D6 gene as potential biomarkers of tre
Freight transportation security concerns both public and private sector institutions, yet their interests are often misaligned, resulting in tensions and trade-offs between performance criteria. Previous research overlooks the connection of public and private interests and provides a fragmented view of the institutions that impact operational conditions and performance within freight transportatioFreight transportation security concerns both public and private sector institutions, yet their interests are often misaligned, resulting in tensions and trade-offs between performance criteria.

Aims: CT acquisition parameters and reconstruction techniques may affect the accuracy of calcium scoring measurements with a potential impact on clinical decision making. We evaluated the agreement of half- versus standard-dose protocols for assessment of aortic valve (AVCS HD and AVCS SD protocols) and coronary artery calcium scoring (CACS HD and CACS SD protocols) with and without the applicatio
